Michael Jackson's children have decided they want to fly to Wales to catch the upcoming MJ Tribute Concert in person ... despite the fact they're getting pushback from two of their famous uncles.

An MJ family rep tells us, "Paris, Blanket and Prince have been asked to attend the MJ Tribute in Wales and they have decided to go."

The rep adds, "They are extremely excited and they're hoping they will have the opportunity to contribute in some way by making a speech. Nothing has been set in stone yet for how they can help, but they really hope they can. "

However, we're told, "Jermaine and Randy are fighting it."

As TMZ previously reported, the two brothers feel the timing of the tribute is "inappropriate" -- explaining, "We find it impossible to support an event that is due to take place during the criminal trial surrounding Michael's death."
